Abstract: Abstract of the Disclosure Improved systems, apparatus and methods for measuring downhole parameters in a well being drilled in the earth with apparatus comprising a drill string, a mud pump for circulating drilling fluid, and flow restriction means located near the bottom of the string so as to cause a pressure drop between the restriction means and the borehole annulus that surrounds the drill string.  In accordance with one aspect of the invention, the improvements involve downhole pulser means for generating negative mud pressure pulses which are utilized to transmit information concerning downhole parameters to above ground equipment.  The improved downhole pulser means utilizes valve means to bypass the restriction means in a manner that results in the efficient generation of effective pulses with minimum expenditure of electric energy. In accordance with another aspect of the invention, improved structure is provided for housing the pulser means and for accommodating associated downhole apparatus.  In accordance with another aspect of the invention, improved methods are provided for extracting negative mud pressure pulse signals from interfering signals resulting from mud pressure variations due to the mud pump means.  In accordance with a further aspect of the invention, improved direct current downhole power supplies are provided.

Abstract: ABSTRACT OF THE DISCLOSURE          The disclosure is of a tool which is used for splitting sections of wood into smaller pieces  In this invention a handle is secured to a wedge shaped metal piece with a ridge on one side, and to this piece a second driving metal piece is fastened in such a manner that it is allowed to travel slightly on a shaft extending from the first wedge shaped metal piece, and as its center of gravity is off-centered from the center line of the wedge shaped piece it causes a twisting or prying motion to be applied to the wood being split. Between the two metal pieces a rubber washer is secured, to temporarily absorb the energy produced by the downward force of the driving metal piece, and then to immediately release said energy into the wedge shaped piece of metal.

Abstract: ABSTRACT A data storage cartridge has a single reel around which is wound a length of magnetic recording tape.  Attached to the lead end of the tape is a cylindrical ferrule which is disposed such that its bore is accessible from below.  The cartridge is used in a spiral recorder/player which includes a carrier having a raised position and a lowered position.  In the raised posi-tion the carrier receives the cartridge through a feed slot in the player housing.  When the carrier is lowered a pin to which is attached an end of a leader tape mates with and is latched to the ferrule.  The other end of the leader is attached to a takeup reel and in this way the tape may be driven by a motor past read/write heads.  Damage to guides, recording heads, idlers, etc. by the ferrule as it is drawn thereacross is avoided by providing cam rings on the guides, idlers and recording head assembly.  These cam rings engage the ferrule and lift it out of the path of the various components mentioned above.

Abstract: ABSTRACT OF TEE DISCLOSURE        A portable gas-fired fastener driving tool in which the tool cannot be operated until the combustion chamber is closed and the combustion chamber cannot be reopened after ignition until the trigger is released.          The operation of the trigger is permitted by the actuation of a bottom trip mechanism which controls the movement of a sleeve mechanism that regulates the opening and closing of the combustion chamber.  During the driving action, the combustion gases above the piston are evacuated through valved openings in the cylinder adjacent the bottom thereof.  The piston contacts a bumper at the bottom of its travel and the difference between the vacuum in the combustion chamber and atmospheric air acts to return the piston to its driving position.

Abstract: APPLICATION OF             DAVID B. WAMSTAD AND DOUGLAS W. WILDA            FLUID PRESSURE TRANSMITTER ASSEMBLY       ABSTRACT    A fluid differential pressure transmitter assembly includes a presure sensor housing having a spacer within the housing to minimize the internal fill fluid used to conduct fluid pressure from a fluid inlet port to a pressure sensor located within the housing in the form of a pressure responsive diaphragm.  Input pressures are applied to respective sides of the diaphragm to produce an electrical signal output representative of the differential pressure from piezoresistive elements deposited on the diaphragm.  The sensor is electrically connected by flexible wires to electrically conductive paths supported on an end surface of the spacer.  The conductive paths are, in turn, electrically connected to electrode wires at electrically conductive support junctions between the spacer and the electrode wires.          However, the spacer is supported on the electrode wires at the support junctions in a free floating arrangement without any other physical contact to either adjacent elements within the housing or the interior wall of the housing.  Thus, physical changes to the spacer such as those occasioned by temperature changes are not transmitted to the fluid seals.  The electrode wires are arranged to pass through fluid-tight seals in the transmitter housing to provide external electrical connections to the sensor while supporting the spacer within the housing.
